Description

Technical Field

[0001] The utility model belongs to the technical field of packaging bottles, and particularly relates to a bottle cap for solving the leakage problem of ceramic wine bottles. Background Art

[0002] During the production process of daily-use bottles, such as ceramic bottles and glass bottles (hereinafter referred to as bottles), thermal expansion and contraction will occur during the firing process, causing irregular shrinkage of the bottle mouths of a small number of bottles. The bottle caps currently used to seal bottles are uniformly produced through molds. The bottle caps produced by molds are generally made of plastic, and the specifications of the produced bottle caps are consistent. When the bottles are filled with wine and sealed with current bottle caps, the finished bottles are circulated in the market. Due to thermal expansion and contraction, the bottle mouth size error occurs, so the bottle mouth is irregular. In addition, the pressure difference between the inside and outside of the wine bottle sometimes causes leakage. Especially at this stage, many wine bottles are shipped by logistics, and leakage is even more obvious. Therefore, it has always been a pain point during the shipping and transportation process. Utility Model Content

[0003] The utility model aims to provide a bottle cap for solving the leakage problem of ceramic wine bottles, so that the bottle mouth can be sealed by the bottle cap for solving the leakage problem of ceramic wine bottles, and the sealing and leakage prevention can be achieved when the size of the bottle mouth is within a certain error range.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] In one embodiment, a bottle cap for solving the problem of leakage of ceramic wine bottles is provided. Figure 1-3 As shown, the bottle cap for solving the problem of leakage in ceramic wine bottles includes a cover sleeve 1 and a cap 2. The cover sleeve 1 is through-through from top to bottom. The cover sleeve 1 is used to be placed on the bottle mouth 31 of the wine bottle 3. A first connecting structure 11 for connecting to the bottle mouth 31 is provided at the lower portion of the inner wall of the cover sleeve 1. The outer wall of the bottle mouth 31 of the wine bottle 3 is provided with a connecting structure that matches the first connecting structure 11. A gasket 4 for sealing the top of the bottle mouth 31 is provided in the middle portion of the cover sleeve 1. The size of the gasket 4 is similar to or slightly larger than the area of ​​the top of the bottle mouth 31. A limiting step 12 is provided in the middle portion of the cover sleeve 1, and the gasket 4 is located below the limiting step 12. A liquid diversion hollow tube 5 is provided in the upper portion of the cover sleeve 1. The lower end of the liquid diversion hollow tube 5 is a pointed tip for puncturing the gasket 4. The cap 2 is used to be installed on the top of the cover sleeve 1 to keep the cover sleeve 1 clean.

[0020] The bottle cap for solving the problem of leakage in ceramic wine bottles is used as follows: (1) Installation on the wine bottle: The lower part of the cover sleeve 1 is placed on the bottle mouth 31 of the wine bottle 3, and is fixedly connected to the bottle mouth 31 through the first connecting structure 11. At this time, the gasket 4 is pressed between the top surface of the bottle mouth 31 and the limiting step 12. Since the cover sleeve 1 and the bottle mouth 31 are connected through the first connecting structure 11, the top surface of the bottle mouth 31 presses the gasket 4, so that the gasket 4 presses and seals the bottle mouth 31; then the liquid diversion hollow tube 5 is installed on the upper inner part of the cover sleeve 1, and the installation position of the liquid diversion hollow tube 5 is such that the tip of its lower end does not contact the gasket 4, and the cap 2 is installed on the top of the cover sleeve 1. (2) Opening the bottle: Remove the cap 2 from the top of the cover 1, and press the liquid guide hollow tube 5 downward from the cover 1, so that the liquid guide hollow tube 5 moves downward along the inner wall of the cover 1 until the tip of the bottom of the liquid guide hollow tube 5 pierces the gasket 4. The tip of the bottom of the liquid guide hollow tube 5 is similar to the needle tip of a syringe needle. After piercing the gasket 4, the liquid in the wine bottle 3 can be poured out from the liquid guide hollow tube 5.

[0021] This bottle cap for solving leakage problems in ceramic wine bottles can seal the bottle mouth. Compared to traditional bottle cap sealing methods, this seal is achieved by pressing a gasket 4 between the upper surface of the bottle mouth 31 and a limiting step 12 within the cover sleeve 1. As long as the bottle mouth size is within a certain tolerance range, the gasket 4 can completely cover the top surface of the bottle mouth 31 to achieve a leak-proof seal, effectively solving the sealing problem caused by dimensional errors caused by thermal expansion and contraction during the glass bottle manufacturing process. Because a liquid diversion hollow tube 5 is provided within the cover sleeve 1, when opening the bottle, the cap 2 is removed and the gasket 4 is pierced through the liquid diversion hollow tube 5, making bottle opening more convenient.

[0022] Furthermore, in another embodiment, Figure 1-3 As shown, the first connection structure 11 of the bottle cap for solving the leakage of ceramic wine bottles is an inner flange arranged at the bottom of the inner wall of the cover sleeve 1, and an outer flange is correspondingly provided on the outer wall of the bottle mouth 31 of the wine bottle 3. The cover sleeve 1 and the bottle mouth 31 are pressure-assembled so that the inner flange is stuck on the lower side of the outer flange.

[0023] Furthermore, in another embodiment, Figure 1-2 As shown, the upper edge of the inner flange of the bottle cap for solving the leakage of ceramic wine bottles is provided with an anti-detachment hook groove, and the corresponding lower edge of the outer flange arranged on the outer wall of the bottle mouth 31 of the wine bottle 3 is also provided with an anti-detachment hook groove, so that the inner flange is not easy to detach after being stuck on the lower side of the outer flange.

[0024] Furthermore, in another embodiment, Figure 1-3 As shown, the gasket 4 of the bottle cap for solving the leakage problem of the ceramic wine bottle is a food-grade latex gasket, which has good elasticity and can form a good seal. In addition, the food-grade latex is acid-resistant and corrosion-resistant and can be used for a long time.

[0025] Furthermore, in another embodiment, Figure 1-3 As shown, the upper portion of the cover sleeve 1 of the bottle cap for solving the leakage of ceramic wine bottles is provided with an inwardly tapered section 13 for installing the liquid guiding hollow tube 5. The inner diameter of the inwardly tapered section 13 is smaller than the inner diameter of the bottle mouth 31 of the corresponding wine bottle. The inwardly tapered section 13 is specifically used to assemble the liquid guiding hollow tube 5 and guide the liquid guiding hollow tube 5 to move downward. Since the inner diameter of the inwardly tapered section 13 is smaller than the inner diameter of the bottle mouth 31, the liquid guiding hollow tube 5 can move downward to pierce the gasket 4 and be inserted into the bottle mouth 31.

[0026] Furthermore, in another embodiment, Figure 1-2 As shown, the cover sleeve 1 of the bottle cap for solving the leakage of ceramic wine bottles is provided with a cap connecting section 14 on the upper side of the inwardly tapered section 13. The inner diameter of the cap connecting section 14 is larger than the inner diameter of the inwardly tapered section 13, so that the liquid diversion hollow tube 5 can be pressed downward from the cap connecting section 14.

[0027] Furthermore, in another embodiment, Figure 1-2 As shown, the cap connecting section 14 of the bottle cap for solving the leakage of ceramic wine bottles is provided with an external thread, and the cap 2 is provided with a corresponding internal thread, and the cap 2 and the cap connecting section 14 are threadedly connected.

[0028] As can be seen from the above embodiments, compared to existing bottle caps, this bottle cap for solving ceramic wine bottle leakage adopts a food-grade latex gasket added to the bottle cap to seal the bottle mouth. Food-grade latex is acid-resistant and corrosion-resistant, and can be used for a long time. In addition, the latex gasket is shrinkable, so when the bottle cap is pressed against the bottle mouth, it is completely clamped by the limiting step. The small gap between the top of the bottle mouth and the bottle cap is also filled by the shrinkage of the latex gasket, which can prevent leakage. Because the bottle cap has a liquid diversion hollow tube with a pointed bottom end, when the cap 2 is opened and slightly pressed downward, the liquid diversion hollow tube follows the slideway in the cover sleeve downward to penetrate the sealed latex gasket, and liquid can be discharged through the liquid diversion hollow tube, thereby solving the leakage problem caused by the irregular bottle mouth. Of course, this bottle cap for solving ceramic wine bottle leakage is not only suitable for sealing wine bottles, but also for sealing other liquid bottles.

[0029] It should be noted that, in this document, terms such as "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements that are inherent to such process, method, article or apparatus.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
